Abstract
A low noise block downconverter structure is characterized in that the structure comprises a main body which is in a shape similar to an electric torch and provided with an installation part, and a printed circuit board (PCB) fixed on the installation part of the main body; a cylinder structure with inner threads is disposed on the right side of the installation part; the cylinder structure is of a straight head type; an F connector is installed on the cylinder structure of the installation part through outer threads; the PCB board is covered by a spacing support; and the spacing support is fixed on the installation part of the main body through screws. The structure provided by the utility model is simple in overall structure and reduced in weight, and can help effectively reduce the direct cost of the main body; with adoption of the straight head type of the F connector, the assembly becomes convenient, assembling steps can be reduced, and workers do not need to be trained, thereby effectively raising production efficiency; at the same time, the whole structure is excellent in water repellency, the service life of the structure is prolonged, and the problem that the direction of the F connector of each product needs to be changed because of different receiving angles is solved.
Description
Technical field
The utility model discloses a kind of tuner structure.
Technical background
Tuner (being LNB), full name is low noise frequency reducing amplifier, the abbreviation of English name Low noise block downconverter; Because satellite signals are larger in the more and more higher signal loss of frequency of arriving at antenna and the transmission of quite faint and coaxial cable, improve so just need LNB to do; The workflow of LNB is after first satellite high-frequency signals being amplified to hundreds thousand of times, to recycle local oscillation circuit high-frequency signals is converted to intermediate frequency 950MHz-2150MHz(according to LNB kind decision intermediate frequency range), be beneficial to the transmission of coaxial cable and the solution mediation work of satellite receiver.The problems such as existing LNB ubiquity complex structure, weight is large, cost is high, assembling is difficult.
Utility model content
The purpose of this utility model is to provide a kind of low cost, tuner structure simple in structure.
To achieve these goals, the utility model adopts following technical scheme:
A kind of tuner structure, it comprises: the body of a similar flashlight shape, described body is provided with installation portion; Also comprise a pcb board, described pcb board is fixed on the installation portion of body; The right side of described installation portion is provided with tapped column structure; Described column structure is straight peen formula; One F head is arranged on by external screw thread on the column structure of installation portion; On described pcb board, be stamped a spacer; Described spacer is screwed on the installation portion of body.
Preferably, described body and installation portion are integral type structure.
Preferably, described spacer is fixed on installation portion by three screws.
The utility model structural entity is simple in structure, weight reduction, can effectively reduce the direct cost of body; Straight peen formula, is brought great convenience to assembling point-blank, can well reduce assembly working link, and workman need not train just can be on duty, effectively enhances productivity; Meanwhile, overall architecture good waterproof performance, has extended useful life, has also solved the problem that need to change F direction of each product because of the angle problem of reception.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Wherein: 1, body; 2, pcb board; 3, F head; 4, spacer; 5, screw; 6, installation portion; 7, column structure.
Embodiment
As shown in Figure 1, a kind of tuner structure of the present embodiment, it comprises body 1, pcb board 2, F 3, spacer 4 and screw 5; Body is similar flashlight shape, is provided with installation portion 6 on body; Pcb board is fixed on the installation portion of body; The right side of installation portion is provided with tapped column structure 7; Column structure is straight peen formula; One F head is arranged on by external screw thread on the column structure of installation portion; Spacer covers on pcb board; Spacer is to be screwed on the installation portion of body.
As an aspect of the utility model embodiment, body and installation portion are integral type structure.
As another aspect of the utility model embodiment, spacer is fixed on installation portion by three screws.
Like this, adopt straight peen formula at column structure place, make that overall structure is simple, weight reduction, can effectively reduce the direct cost of body; Straight peen formula, is brought great convenience to assembling point-blank, can well reduce assembly working link, and workman need not train just can be on duty, effectively enhances productivity; Can add that at F head place teething ring and plastic casing support the use, when use, can form a complete entirety, play the effect of real waterproof, allow product longer service life, more reliable; This structure effectively solves F direction need to changing each product because of the angle problem of reception, has realized the consistency of each product ontology.
The foregoing is only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
